    Pre-breathing procedure

    Diving my rEvo, I changed the procedure and close O2 every time until just before I jump into the water (usually it takes us quite some time from doing the pre-jump check on the car until I walked to the water and waited for my buddy;-)). The reason why I do this is not (primarily) to save O2 -...

    Hydros Pro

    I bought my Hydros Pro in Oct. 2018 and have meanwhile 400 dives on it. I love how it feels under water (trim, handling...). Great for traveling and even good for coldwater diving with lots of weights in the pockets. My Tec-Buddies usually don't like it (without trying it) just because there is...

    Is it worth to do OC trimix before CCR Helitrox?

    Nowadays (he prices), I would definitely save the money and time and skip OC TX courses. There is no big miracle about brething a helium mix in general and theoretical and practical knowledge of that is not different from breathing it OC and CC. However, I personally benefited a lot from...

    Seriously, though... you're wearing your weights too high

    Totally agree to dour findings. I came to the same conclusion and then entirely removed the top weight patches on my rEvo and instead added some pockets at the very bottom (in between the stand). on top of that I shifted my BO tanks further back. I now have reached awesome stability even if...

    Importance of CO2 and scrubber life sensors

    If you use your Rebreather as I do, which is 2-3 times a week, like other divers are doing recreational dives, a scrubber monitoring is not just a great safety feature but also giving you a lot more scrubber time without compromising on safety. At least this is true with rEvo‘s dual scrubber/...

    Late March Red Sea - Which sections?

    Check out the „Blue Melody“ starting April 29th: 10 days „ultimate Red Sea tour“. I would do something like this plus a few days diving from a nice resort (Mövenpick Qusir). Keep in mind, on an one week safari, you usually have only five and a half days of diving..

    Late March Red Sea - Which sections?

    Hi, I probably repeat myself, but July is not necessarily better for sharks in the red sea than March/April. So I disagree on this with Christian. As most of you probably know, most Sharks rather don‘t like super-warm water with no current and Egypt in Summer is super-warm. The truth is: every...

    Sharm or Quseir/Marsa Alam...?

    I can highly recommend the Quseir area (e.g. the Mövenpick resort). IMO the best shore / non-liveaboard diving in Egypt. Egypt is definitely not fully back to normal (I have been there in the second week of Dec), but it‘s open and you will not miss anything. Sinai is pretty much off the table...

    Late March Red Sea - Which sections?

    Hello, maybe some additional information about diving in Egypt which you would like to factor in: Are you directly coming from the States to Egypt? I assume that‘s going to be your first trip to Egypt, correct? Mid-to-late March is still the very beginning of the Liveaboard season. That‘s not...

    Where to dive in Bavaria (Germany)?

    As you can probaly imagine, diving in Germany is year around cold and dark. It’s nothing where you should just jump in with coral reef experience/ equipment (forget about the legal discussion above. There are lakes where you are allowed to dive with or without a dive center). You have to go for...

    Riding deco ceiling on ascent

    I wished, Shearwater would give the option of a "non-discrete stop value" in 0.1m in addition or instead of the 3m/10ft steps (warnings should be adapted). This "ceiling" value should be according to the GF values chosen (not based on Bühlmann 100/100 - I think that's already the case at the...

    Dil switch off helium during deco

    Thanks - I wasn‘t aware of that ICD is judged as a no-brainer in the meantime.

    Dil switch off helium during deco

    Not sure if I fully understand what you are suggesting. Are you considering to switch your innert gas mix from HE heavy to N heavy to safe a few minutes Deco time? If so, I think that‘s a terrible idea (no offence) due to „isobaric counter diffusion“. I would not increase my pN2 by more than 0.5...

    Frequent CCR divers, what do you do between dives?

    rEvo: Ease of cleaning is probably one of the advantages of this model, not highlighted enough. Diving in freshwater (essentially drinkingwater quality). After the diving day: 1. put off the breathing loop and rinse it: 2-3minutes 2. remove yellow lid to open counter lungs and remove yellow...

    Measure scrubber runtime?

    [My point about the Revo is that it's pretty much a binary measurement when the second scrubber begins to be used and warms up. This gives an absolute reading that half of the scrubber has been used (actually slightly more as it's measuring the second scrubber, but round it to half). This...
